Yuxin Tan updated FLINK-31634:
------------------------------
    Release Note: Hybrid Shuffle supports storing the shuffle data in remote 
storage. The remote storage path can be configured with the option 
`taskmanager.network.hybrid-shuffle.remote.path`. Hybrid Shuffle uses less 
network memory than before by decoupling the memory usage from the number of 
parallelisms, improving the stability and ease of use.  For detailed 
information, please refer to 
https://nightlies.apache.org/flink/flink-docs-master/docs/ops/batch/batch_shuffle/#hybrid-shuffle
  (was: This introduces a new Hybrid Shuffle mode to support remote storage. 
The remote storage path is specified by 
`taskmanager.network.hybrid-shuffle.remote.path`.  The new mode has resolved 
existing issues in the legacy Hybrid Shuffle mode. Firstly, the new mode uses 
less required network memory. Secondly, the new mode can store shuffle data in 
remote storage when the disk space is not enough, which could avoid 
insufficient disk space errors. The new mode is only enabled when 
`taskmanager.network.hybrid-shuffle.remote.path` is configured.

Currently, the new Hybrid Shuffle mode is in an experimental phase. In case of 
unexpected issues, the new mode can fall back to the legacy mode by setting 
`taskmanager.network.hybrid-shuffle.enable-new-mode` to `false`. Once the new 
mode is stable, the legacy mode and the fallback option will be removed.)
